Flap gate structure

Abstract

The invention discloses a flap gate structure which comprises a gate plate. More than one flood discharging plate is installed on the gate plate and vertically and evenly arranged on the gate plate. A buttress is installed on one side of the gate plate and is of an irregular structure. One side of the buttress is embedded in the gate plate. The buttress is fixedly connected with the gate plate. A hinged chain is connected to the lower surface of the buttress in a welded mode. A connecting rod is arranged on the hinged chain and connected with the hinged chain through a chain buckle. One end of the connecting rod is connected with the hinged chain, and the other end of the connecting rod penetrates through a limiting plate to be connected with a limiting groove formed in the limiting plate. The connecting rod is connected into the limiting groove in a sliding mode. A fixing plate is further arranged on the limiting plate and arranged below the limiting groove. By means of the flap gate structure, a gate can be conveniently opened and closed, complex connecting modes are eliminated, operation is simpler, and the water level can be efficiently controlled; in addition, the good connecting performance is achieved, and impact resisting and vibrating of the flap gate can be effectively eliminated.

Description

Technical field [0001] The invention relates to a gate structure, in particular to a flap gate structure. Background technique [0002] With the continuous decrease of global water resources reserves, the living environment of human beings is continuously deteriorating, and water shortages and water cuts occur from time to time. In order to improve the reuse rate of water resources and reduce the waste of water resources, the construction of various water storage dams has become the main way for humans to transform nature, develop and utilize water resources, and gates are indispensable in water storage dams. Water conservancy facilities. The general automatic control flap gate is a kind of arc wheel link type flap gate. There are grooves on the arc wheel. When the water level exceeds the storage design water level, the torque generated by the water thrust of the upper part of the flap gate is greater than the lower part of the fulcrum. The torque generated by the water thrust ...

AI Technical Summary

Problems solved by technology

The general self-controlled flap gate is a kind of arc wheel connecting rod type flap gate. There are grooves on the arc wheel. When the water level exceeds the design water level of the water storage, the torque generated by the water thrust on the upper part of the flap gate is greater than that on the lower part of the fulcrum. The torque generated by the water thrust slides up and down in the arc-shaped wheel through the guide plate to make the gate plate and the outrigger flip around the fulcrum, thereby opening the gate. However, the guide plate is narrow and is clamped in the arc-shaped wheel, not only the space is limited , and it is easy to cause cracking of the outriggers, which will eventually affect the safe operation of the gate
